"The pressure is not stable after the vacuum pump is evacuated, so the analysis result is definitely not accurate

On June 15, when Yin Kaigong, the monitor of the comprehensive (product) analysis area of the Guangzhou Petrochemical Inspection Center, was measuring the saturated vapor pressure of gasoline, he found that the instrument could not stabilize

Gasoline saturated vapor pressure is one of the important indicators of oil products, and it is a key factory inspection item

"It should be the presence of foreign matter in the vacuum system, which caused the leak tightness to fail to meet the standard

In order to confirm his judgment, Zhaoyang immediately consulted the technicians of the instrument manufacturer and got a reply that "there is foreign matter in the miniature solenoid valve"

"Since the foreign matter cannot be eliminated by solvent washing, can we try to use compressed air to clean it

They said nothing.

The effort paid off.
